2017 - $140.5m revenue and EBITDA ~19.4m (13.8% margin)
2018 - $162m revenue and EBITDA ~23.65M (14.6% margin)
=+20% EBITDA for the year on lowest targets. Don't underestimate the growth in the EBITDA margin.
The company was already phasing out commoditised work and to me seems to be positioned well for future growth.
